not sure this helps prevent crashes. perhaps "helps mitigate downtime" ?

i dont think it is limited to remote filesystems

what about CONFIG_NFSD_V4 ? that looks like NFSv4 as a server to me ...

with ntfs3g (built on FUSE), i dont think this is an accurate
statement. even if your focus is purely on in-kernel fs's, this is at
least a bit misleading.

i dont think "Atmel" is an architecture. i think you meant "AVR32".

i'm pretty sure at least Linux 2.4 had support for IPv6.

i think there's also support for multi transmit ? or has that not

the inclusion of the soft mac80211 stuff is pretty note worthy

"correct" is a bit awkward. how about "right" ?

definitely would be useful to have "CAN" in here

one of the other major reasons for CAN is robustness is the high noise
